JSF and A400M at risk?

[Modern Elmo]

... The two X-32 prototypes featured a delta wing design, which was chosen to minimize production manufacturing costs. However, eight months into construction of the prototypes, the JSF's maneuverability and payload requirements were refined at the request of the Navy and Boeing's delta wing design fell short of the new targets. Engineers put together a new design with a conventional tail (narrowly beating out a Pelikan tail) with reduced weight and improved agility, but it was too late to change the prototypes. It was judged that they would be sufficient to demonstrate Boeing's technology.[3]
